Why is `True` in Python not colored properly?

Should be this when semantic highlighting is enabled, I had to manually edit it in the settings.json file:

Code Snippet

def validateInteger(prompt):
    while True:
        try:
            return int(input(prompt))
        except ValueError:
            print("That's not an integer!\n")
            continue

The language is Python

Notes

This is with semantic highlighting enabled.
